(a) Active arming mode:
This system operates as described in the diagram below when one of the items for each condition is met.
w/ Smart Key System
Condition |
Item |
---|---|
Condition [1] |
In disarmed state 1, when the ignition switch is off, the system state is switched if the following condition is met:
In disarmed state 1, when the ignition switch is off, the engine hood is closed, and all doors are locked, the system state is switched if the following condition is met:
|
Condition [2] |
Allow approximately 30 seconds to elapse. |
Condition [3] |
|
Condition [4] |
|
Condition [5] |
|
Condition [6] |
After approximately 57 seconds, alarm stops and system returns to armed state. |
Condition [7] |
The engine hood is closed |
Condition [8] |
|
Condition [9] |
In disarmed state 1, when the ignition switch is off, the system state is switched if the following condition is met:
In disarmed state 1, when the ignition switch is off, the engine hood is opened, and all doors are locked, the system state is switched if the following condition is met:
|
Condition [10] |
The engine hood is opened |
Condition |
Item |
---|---|
Condition [1] |
In disarmed state 1, when the ignition switch is off, the system state is switched if the following condition is met when the key is not in the key cylinder:
In disarmed state 1, when the ignition switch is off, the engine hood is closed, and all doors are locked, the system state is switched if the following condition is met when the key is not in the key cylinder:
|
Condition [2] |
Allow approximately 30 seconds to elapse. |
Condition [3] |
|
Condition [4] |
|
Condition [5] |
|
Condition [6] |
|
Condition [7] |
With the engine hood closed |
Condition [8] |
|
Condition [9] |
In disarmed state 1, when the ignition switch is off, the system state is switched if the following condition is met when the key is not in the key cylinder:
In disarmed state 1, when the ignition switch is off, the engine hood is opened, and all doors are locked, the system state is switched if the following condition is met when the key is not in the key cylinder:
|
Condition [10] |
The engine hood is opened. |
4. FORCED DOOR LOCK CONTROL
(a) The forced door lock control prevents the vehicle from being tampered with. Immediately after a door is unlocked (armed starts), all doors are forced to lock by a forced door lock signal.
(1) If the following conditions are met, the forced door lock control is operated.
5. ALARM MEMORY FUNCTION
(a) If the alarm is set off (tampering is detected) while the theft deterrent system is armed, it will be stored by the alarm memory function. Whenever the theft deterrent system is canceled, the alarm memory function causes the taillights to light up for 2 seconds in order to inform you that the alarm has been set off.
(1) Conditions that cause the taillights to light up for 2 seconds:
The theft deterrent system has entered the alarm sounding state (tampering has been detected) at least once.
HINT:
Active arming mode: See Active Arming Mode.
6. PANIC ALARM CONTROL (w/ PANIC Switch)
HINT:
Security horn does not sound when the panic alarm control is operated.
(a) The panic alarm control makes it possible to voluntarily set off the panic alarm by pressing the panic switch on the wireless transmitter.
(1) Conditions that cause the panic alarm control to set off the panic alarm:
The panic switch on the wireless transmitter is pressed under the following conditions:
(2) Conditions that cause the panic alarm control to shut off the alarm:
Any of the following conditions is met during panic alarm operation:
7. SECURITY INDICATOR LIGHT OUTPUT
(a) According to the state of the theft deterrent system, the main body ECU (multiplex network body ECU) outputs a signal to turn the security indicator light on. However, some of the actual lighting conditions of the security indicator light are different from the output signals of the main body ECU (multiplex network body ECU).
